Question

A person pushes a 23.6-kg shopping cart at a constant velocity fora
distance of 18.4 m on a flat horizontal surface. She pushes in
adirection 27.7 ° below the horizontal. A 44.1-N frictionalforce
opposes the motion of the cart. (a) What isthe
magnitude of the force that the shopper exerts? Determine thework
done by (b) the pushing force,(c)
the frictional force, and (d)the gravitational
force.
